The Easiest Way to Upgrade Your Downlight Globes The Philips Master LED MR16 6.5W is designed to work with your existing downlight fittings, transformers, and dimmer switches (if present). All you need to do is swap the globes. Compared to an old halogen MR16 downlight bulb, you'll get: An 85% reduction in energy usage and cost, Equivalent or higher brightness, An incredible 25-year expected lifetime when used for four hours per day. Trusted Philips Quality - Over 10 Years in The Making Over the last ten years, Philips has improved the efficiency and features of this product. It now sports its lowest-ever energy usage, highest brightness, and best colour rendition. We only sell the latest Philips Master LED MR16 6.5W - the 'New Model' pictured above. The new model has a much cleaner design than previous versions. Furthermore, it has a higher colour rendition index (CRI) of 90, compared to 80 on the older models. A higher CRI means they produce a much higher quality of light. Choose Your Preferred Colour Temperature Colour Temperature describes the colour of the light produced by the downlight bulb. Use the description and graphic below to make your choice. Warm White 2700K - This is a popular choice because it's a true warm white, just like an old-fashioned halogen MR16 bulb. Warm White 3000K - This is a slightly whiter and brighter colour and is our best-selling variant. We recommend this option if you are unsure which to choose. Cool White 4000K - This is closer to daylight or a fluorescent tube in the colour it produces. Some customers prefer this colour to achieve maximum brightness. Select the Best Beam Angle Beam Angle refers to the angle of light emitted from the MR16 LED. There are two beam angles to choose from: 60˚ (Wide Beam) - For regular ceilings or where lights are spaced further apart. This is the most popular choice, and we recommend it for most situations. 36˚ (Narrow Beam) - For high ceilings or where lights are installed quite close together. It is also used in accent lighting, for example, to light up a painting or artwork. This graphic shows the light spread at floor level of the two different beam angles for a ceiling height of 2.7m.

Frequently Asked Questions - Philips MR16 LED Will it work on non-dimmable circuits? It works on dimmable and non-dimmable circuits (with and without dimmers installed). Will the MR16 LED work with my transformer? It works with the vast majority of existing transformers. This includes old 'iron-core' transformers and the newer 'electronic' variety. Will the MR16 LED work with my dimmer? It has extensive dimmer compatibility. Should you encounter a problem with your dimmer, there are several solutions available, such as: Leaving one halogen bulb in the circuit to increase the load, or Replacing the dimmer with one that is known to work with LEDs (such as this LED dimmer), or Removing the dimmer switch. Does it work with specialist lighting systems such as C-Bus? We've received good feedback from customers using the Philips Master LEDs in their C-Bus wired homes and businesses. However, if you use a specialist lighting control system like this, we recommend buying several globes to test out before undertaking a complete upgrade. Will it fit in my existing downlight fitting? Yes, it mimics the shape of halogen bulbs almost exactly. If you have cause for concern, double-check the dimensions graphic above, and buy a few to try out first. What other options are available?
